In addition, I have provided means for securely anchoring the buck to the floor and ceiling by means oi a metal angle so positioned as to furnish the n'iazzinium rigidity for the Weight of material y employed.

rIhe exact form and arrangement of the parts is not essential for the accomplishment oit the desired purpose and I do not wish to be limited except as indicated in the appended claims,

I claim:
